Sammartino died Wednesday at the age of 82, according to WWE. The “Italian Superman” held numerous titles and was the WWE’s longest-reigning world champion which ESPN says he held for nearly eight consecutive years.

Mars was born Peter Gene Hernandez, but was nicknamed “Bruno” by his father because he was a huge fan of the wrestler. His dad said the inspiration for the nickname was because Mars was a “chunky” baby — and Sammartino was about 275 pounds at his prime wrestling weight.
